Why Us
Today, sleep advice often comes from non-medical sources. What makes us different is that our care is led by doctors who specialise in sleep medicine. We focus on accurate diagnosis and evidence-based treatment, so your care is guided by science — not sales.
We provide care for a wide range of sleep concerns, including:
Diagnostic Sleep Studies
Sleep Apnoea & CPAP
Insomnia
Circadian Rhythm Disorders
Parasomnias
Restless Legs
Hypersomnolence
We provide care for people aged 16 and above
How We Work
We offer both in-person and video sleep physician consultations.
Sleep medicine is well suited to virtual care, with assessment based largely on your clinical history and sleep study results. Video consultations provide secure and convenient access to specialist care.
CPAP trials and home sleep studies are arranged through our Greenlane clinic and, when appropriate, can be mailed to you.
Testing Options
While many sleep studies are available in the community, the quality and information they provide can vary.
Following your consultation, we select the most appropriate test for your needs, providing reliable results and evidence-based treatment recommendations.
